Yes, they matter, and no, for some reason we have never covered them in the FAQ. They only seem to matter to PC users, not Mac users. All the letters of the alphabet and all numbers are fine. Dashes and underscores (- _ ) are fine. Slashes ( / ) are fine. I avoid all others. I *think* ampersands ( & ) may be fine. I'm a Mac user, so to be honest, I haven't paid a whole lot of attention. But, I name my torrents as band yyyy-mm-dd. I don't put in bootleg titles or any of that stuff. I try to keep it simple.
